Compatibility with Australis Rated 4 out of 5 stars

Ref: https://developer.mozilla.org/en-US/Firefox/Australis_add-on_compat

With Australis, there is no status bar anymore. The add-on may need to be modified to be compatible. I tried to install the add-on on Firefox Nightly (30.01a) and there seems no way to access the add-on buttons in Australis.
